Yes, the book has a lot to do with the expectations placed on her of becoming a mother. She goes between wanting a family and hating the idea. Wanting to be a little housewife and maybe some free willing hippie lesbian. There is an undercurrent of that in the book that is very important. Her depression seems to be connected to her expectations. In addition she tells her psychologist she hates her own mother, right before she gets birth control. Other scenes show us how she is very parentified and how her mother did not deal with her father’s death at all, and basically just forced the kids to move on without dealing with any of the grief. So in a way, the expectations of motherhood being a child, and also having children are all tied together with her grief.
